- H01J 2225/36 Tubes in which an electron stream interacts with a wave travelling along a delay line or equivalent sequence of impedance elements, and without magnet system producing an H-field crossing the E-field
- H01J 2225/42 Tubes in which an electron stream interacts with a wave travelling along a delay line or equivalent sequence of impedance elements, and with a magnet system producing an H-field crossing the E-field
- H01J 2225/48 Tubes in which two electron streams of different velocities interact with one another, e.g. electron-wave tube
- H01J 2225/49 Tubes using the parametric principle, e.g. for parametric amplification
